A novel dual switch quadratic Zeta architecture

with a broad conversion ratio and non-inverting output voltage

features is present in this paper. It has broader bucking

characteristics in comparison to the Zeta converter and provides

a continuous source current. The theoretical circuit analysis

and subsequent simulation will verify the features. The transfer

function is realized via state-space modeling, and pole-zero plots

are compared with the traditional Zeta converter topology to

elaborate on its stability. PI controller is designed to improve the

stability of the circuit by increasing the gain/phase margin and

response speed of the sixth-order system.
